This project utilizes a rotary kiln and secondary combustion chamber system for the incineration of garbage and solid waste, as well as the treatment of hazardous waste gases. This unique and effective solution provides excellent results. The thermal and technical parameters of the main equipment and the treatment process are as follows:
1. Main Equipment Parameters
Rotary Kiln:
Kiln Body Specifications: Φ2200X18000mm
Equipment Inclination: 3:100
Kiln Body Material: Q345R
Rotary Kiln Operating Temperature: 600°C-700°C
Secondary Combustion Chamber:
Secondary Combustion Chamber Material: Q345
Secondary Combustion Chamber Operating Temperature: 1100°C
2. Process Flow
The rotary kiln feed port is equipped with a pusher mechanism to ensure continuous feeding. Solid (hazardous) waste is fed into the rotary kiln through the feed mechanism, where it is incinerated into high-temperature flue gas and ash. The ash enters the slag discharger at the kiln head and is regularly transported to the stabilization/solidification workshop for treatment. The rotary kiln's outlet temperature is 800-850°C. After the flue gas enters the secondary combustion chamber, secondary air is injected tangentially around it, creating a strong vortex field within the chamber, ensuring the complete combustion of the combustible components in the flue gas. The unique structural design of the secondary combustion chamber also enables it to function as a cyclonic dust removal system. The flue gas at the secondary combustion chamber outlet exceeds 1100°C, and the flue gas resides in the high-temperature zone for more than 2 seconds, ensuring the complete decomposition of harmful components in the flue gas, including dioxins, and meeting the requirements for hazardous waste incineration.
The rotary kiln maintains a stable slag layer approximately 50mm thick, which protects the refractory layer.
